Collagen fibril diameters in chordae tendineae show no difference between mitral and tricuspid valves.
Cross-Sectional (n=7)

Similar chordal collagen architecture across valves; leaves open whether this uniformity affects differential regurgitation risk.

Berkovitz et al. (1993) conducted a cross-sectional in Postmortem examination of human chordae tendineae (n=7). Left side of the heart (mitral valve) vs. Right side of the heart (tricuspid valve) was evaluated on Mean collagen fibril diameter (p=NS). Collagen fibril diameters in the chordae tendineae showed no significant differences between the mitral and tricuspid valves (40.5 nm vs 41.1 nm).
